Binocular vision parameters and visual performance in bilateral keratoconus corrected with spectacles versus rigid gas-permeable contact lenses / Parámetros de visión binocular y rendimiento visual en queratocono bilateral corregido con gafas versus lentes de contacto rígidos permeables al gas

Purpose: To analyze binocular vision of individuals aged 18 to 35 years diagnosed with keratoconus, utilizing spectacles and rigid gas-permeable (RGP) contact lenses. Research was led by the Universidad Autónoma de Aguascalientes, México and Fundación Universitaria del Área Andina Pereira, Colombia. Methods: A single center, prospective non-randomized, comparative, interventional, open-label study, in which the differences in binocular vision performance with both spectacles and RGP contact lenses was carried out from December 2018 to December 2019. Sampling was performed according to consecutive cases with keratoconus that met the inclusion criteria until the proposed sample size was reached. Results: Rigid gas-permeable (RGP) contact lenses notably enhanced distance and near visual acuity in keratoconus patients compared to spectacles. Visual alignment analysis shows exophoria at both distances and is slightly higher with RGP contact lenses. The difference was statistically significant (p<0.05), with 82.5 % presenting compensated phoria with spectacles and pnly 42.50% with RGP contact lenses. Stereoscopic vision improved while wearing RGP contact lenses (42.59 %), although accommodation and accommodative flexibility remained within normal ranges. Conclusions: Patients with keratoconus fitted with RGP contact lenses have improved binocular vision skills such as visual acuity, stereopsis, and accommodative flexibility. However, even when the vergence and motor system is decompensated with respect to normal ranges, the range between break and recovery points for both fusional reserves and the near point of convergence (NPC) improves with the use of RGP contact lenses, giving indications of an adaptive condition of the motor system from the medium to the long term.(AU)

Time-dependent association between the economic activity restriction due to health condition and mental illness: Finding from 15-year prospective cohort study

Background and Objectives The Economic Activity Restriction (EAR) due to health conditions is being utilized as a foundational measure for the European indicator Healthy Life Years (HLY). The EAR group is experiencing limitations not only in economic activities but also in overall activities, and it is a population with a high likelihood of transitioning to mental illness due to health condition. However, few studies have investigated the relationship between EAR and mental illness. Therefore, the purpose of this study was to identify the association between EAR due to health conditions and mental illness for those aged 45 and older in South Korea. Methods We obtained data from the 2006–2020 Korean Longitudinal Study of Aging. EAR was assessed using self-reported questionnaires based on the Global Activity Limitation Indicator. mental illness was assessed based on the diagnosis data for participants who had been diagnosed. After excluding missing values, the data of 9,574 participants were analyzed using the chi-square test, log-rank tests, and time-dependent Cox proportional hazard model to evaluate the association between EAR and mental illness. Results Out of the 9,574 participants gathered at baseline, the mental illness rate was 4.8 %. The hazard ratio (HR) of mental illness in those in the “very probable” of EAR was 2.351 times higher (p-value <0.0001) compared with “not at all” of EAR. In model 1 which includes under 64 years, HR of mental illness in “very probable” of EAR was 3.679 times higher (p-value: 0.000) and in “probable” of EAR was 2.535 time higher (p-value: 0.001) compared with “not at all” of EAR. Conclusion If we provide opportunities to participate in community activities or provide the mental health promotion programs for middle-aged population who are experiencing EAR due to health condition...

Effects of antipsychotics on amino acid levels in patients with first-episode schizophrenia: A prospective study

Background and objectives Alterations in the molecular mechanisms of specific amino acids (AAs) may be implicated in the pathophysiology of schizophrenia (SZ). However, little is known about antipsychotic drugs influence on levels of AAs. This study aimed to further explore antipsychotics' effects on AAs and serum lipid levels in first-episode SZ. Methods Eighty subjects with the International Classification of Diseases, Tenth Edition (ICD-10) criteria-defined SZ were enrolled. The levels of 31 AAs were measured in plasma samples using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Results Ten AAs (i.e., citrulline, sarcosine, tyrosine, leucine, proline, hydroxyproline, kynurenine, tryptophan, valine and isoleucine) were observed to be higher and three AAs (i.e., GABA, aminobutyric acid and asparaginic acid) were lower in 80 patients with first-episode SZ after various antipsychotics treatment. In addition, there were 1 out of 31 AAs altered after olanzapine treatment and there were only 2 out of 31 AAs altered after risperidone treatment. Furthermore, serum triglyceride (TG) was markedly upregulated after olanzapine treatment, while Apolipoprotein A1 (ApoA1) was generally upregulated after risperidone treatment in patients with first-episode SZ. Conclusions Taken together, antipsychotic treatment can affect the plasma levels of AAs in patients with first-episode SZ, and olanzapine and risperidone have differential effects on the levels of AAs.

Renin–angiotensin–aldosterone system blockers effect in chronic kidney disease progression in hypertensive elderly patients without proteinuria: PROERCAN trial / Efecto de los bloqueantes del sistema renina-angiotensina-aldosterona en la progresión de enfermedad renal crónica en pacientes hipertensos añosos sin proteinuria: ensayo clínico Progresión de Enfermedad Renal Crónica en Ancianos

Introduction: Evidence about nefroprotective effect with RAAS blockers in elderly patients with chronic kidney disease (CKD) without proteinuria is lacking. The primary outcome of our study is to evaluate the impact of RAAS blockers in CKD progression in elderly patients without proteinuria. Materials and methods: Multicenter open-label, randomized controlled clinical trial including patients over 65 year-old with hypertension and CKD stages 3–4 without proteinuria. Patients were randomized in a 1:1 ratio to either receive RAAS blockers or other antihypertensive drugs and were followed up for three years. Primary outcome is estimated glomerular filtration rate (eGFR) decline at 3 years. Secondary outcome measures include BP control, renal and cardiovascular events and mortality. Results: 88 patients were included with a mean age of 77.9±6.1 years and a follow up period of 3 years: 40 were randomized to RAAS group and 48 to standard treatment. Ethiology of CKD was: 53 vascular, 16 interstitial and 19 of unknown ethiology. In the RAAS group eGFR slope during follow up was −4.3±1.1ml/min, whereas in the standard treatment group an increase on eGFR was observed after 3 years (+4.6±0.4ml/min), p=0.024. We found no differences in blood pressure control, number of antihypertensive drugs, albuminuria, potassium serum levels, incidence of cardiovascular events nor mortality during the follow up period. Conclusions: In elderly patients without diabetes nor cardiopathy and with non proteinuric CKD the use of RAAS blockers does not show a reduction in CKD progression.

Introducción: Actualmente no existe suficiente evidencia sobre el efecto nefroprotector de los bloqueantes del sistema renina-angiotensina-aldosterona (BSRAA) en pacientes añosos con enfermedad renal crónica (ERC) sin proteinuria y sin cardiopatía. El objetivo es evaluar el efecto de los BSRAA en la progresión de la ERC en este grupo poblacional. Métodos: Se trata de un estudio prospectivo, aleatorizado, que compara la eficacia de los BSRAA vs. otros tratamientos antihipertensivos en la progresión renal en personas mayores de 65 años con ERC estadios 3 y 4 e índice albúmina/creatinina<30mg/g. Aleatorización 1:1 BSRAA o tratamiento antihipertensivo estándar. Se recogieron cifras tensionales y parámetros analíticos de un año previo a la aleatorización y durante el seguimiento. Resultados: Se incluyeron 88 pacientes seguidos durante tres años con edad media de 77,9±6,1 años. De estos, se aleatorizaron 40 al grupo BSRAA y 48 al estándar. La etiología de ERC fue: 53 vascular, 16 intersticial y 19 no filiada. En el primer grupo se observó una progresión de la ERC con una caída del filtrado glomerular estimado (FGe) de -4,3±1,1mL/min, mientras que en el grupo estándar un aumento del FGe durante el seguimiento de 4,6±0,4mL/min, p=0,024. No se apreciaron diferencias entre ambos en el control tensional, el número de antihipertensivos, la albuminuria, los niveles de potasio, la incidencia de eventos cardiovasculares ni la mortalidad durante el seguimiento. Conclusiones: En pacientes añosos no diabéticos con ERC no proteinúrica y sin cardiopatía el uso de BSRAA no añade beneficio en la progresión de la ERC.

Epithelial and stromal thickness profile and lens decentration in myopic orthokeratology / Perfil de espesor epitelial y estromal y descentrado del cristalino en ortoqueratología miope

Purpose: To study topographic epithelial and total corneal thickness changes in myopic subjects undergoing successful orthokeratology treatment in connection with the objective assessment of contact lens decentration. Methods: A prospective-observational and non-randomized study in 32 Caucasian myopic eyes undergoing Ortho-k for 3 months. Total, epithelial, and stromal thicknesses were studied before and after Ortho-k treatment, using optical coherence tomography with anterior segment application software. Central, paracentral, and mid-peripheral values are taken along 8 semi-meridians. Results: The central average total corneal thickness was 4.72 ± 1.04 μm thinner after Ortho-K. The paracentral corneal thickness showed no significant changes (p = 0.137), while the mid-peripheral corneal thickness was increased by 3.25 ± 1.6 μm associating this increase exclusively to the epithelial plot (p<0.001). When lens centration was assessed, a lens fitting decentration less than 1.0 mm was found for the whole sample, predominantly horizontal-temporal (87.5%) and vertical-inferior (50%) decentring. Corneal topographical analysis revealed a horizontal and vertical epithelial thickness asymmetric change profile with paracentral temporal thinnest values, and mid-peripheral nasal thickest values. Conclusions: The present study found a central corneal thinning induced by Ortho-k lenses in subjects with moderate myopia, only associated with a change in epithelial thickness, as well as mid-peripheral thickening, that seems to be mainly epithelial in origin. The authors also found a tendency of contact lens decentration toward temporal and inferior areas conditioning an asymmetric epithelial redistribution pattern.(AU)

Job satisfaction of Spanish and Portuguese optometrists / Satisfacción laboral de los optometristas españoles y portugueses

Purpose: Given the increase in demand for optometry services by society and the importance of the Optometry profession in Portugal and Spain, the objective of this study was to determine job satisfaction and important factors related to this satisfaction in a sample of Portuguese and Spanish optometrists. Methods: A prospective, cross-sectional, and observational study was carried out from June to December 2021. An adaptation of the 15-item job satisfaction in eye-care personnel (JSEP) questionnaire validated by Paudel et al. was administered to Portuguese and Spanish optometrists. The questionnaire was shared through different social media (Facebook, LinkedIn, WhatsApp, etc.) in a Google form during the months of June to December 2021 in Portugal and Spain. Results: A total of 530 surveys were collected in Portugal (42.3%; n = 224) and Spain (57.7%; n = 306). The factors that most influence overall job satisfaction are salary, career development opportunities, recognition/prestige in society, good work-life balance (all p<0.001), workplace equipment and facilities, and encouragement reward positive feedback (both p = 0.002). When comparing the determinants of job satisfaction of optometrists, it was found that Portuguese professionals were generally more satisfied than Spanish ones (p<0.001). However, Spanish optometrists reported feeling more supported by their colleagues (p<0.001). Conclusion: This study has shown that the level of job satisfaction was higher in Portugal than in Spain. The most important factors influencing job satisfaction were salary, job stability, and support from colleagues.(AU)

A survey of cancer patients' interest in undertaking exercise to promote relaxation during radiotherapy for breast cancer and metastatic cancer.

BACKGROUND: Approximately 25-50% of patients undergoing radiotherapy (RT) experience psychological distress and anxiety, which can detrimentally affect both their quality of life and treatment outcomes. While previous research has demonstrated that relaxation exercises can enhance the tolerability of RT and alleviate associated stress and anxiety, the specific needs for such therapies in radiation oncology remain under-explored. This study aims to investigate the demand for and preferences toward relaxation exercises among radiotherapy patients, addressing a critical gap in patient-centered care. METHODS: A prospective pseudonymized survey study using a one-time paper-based questionnaire was conducted from 2022 to 2023 among patients undergoing curative-intent RT for breast cancer or patients undergoing palliative RT for bone metastases. Patients were asked in a 11-item questionnaire about their anxiety, pre-existing practice of relaxation exercises/interventions, their interest in relaxation exercises, and preferences on the type and format of instruction. Data were analyzed descriptively. RESULTS: 100 patients (74 female and 26 male) responded, of whom 68 received curative-intent adjuvant RT and 32 palliative RT. Median age was 62 years. 78% of patients indicated a desire to be actively involved in their radiotherapy, but only 27% had used relaxation exercises prior to RT. 44.8% of both curatively and palliatively treated patients who wanted to be actively involved in their therapy desired to learn how to best relax. 56.4% of respondents were willing to spend extra time learning offered exercises. CONCLUSION: The survey indicates that patients undergoing RT, both for curative or palliative intent, desire relaxation exercises to relieve stress and anxiety from RT. It is therefore important to assess the need for relaxation interventions in individual patients and to develop suitable programs or collaborate with other healthcare professionals to meet these needs.

Incidence of tuberculous infection in a TB-endemic city.

Current metrics for TB transmission include TB notifications, disease mortality, and prevalence surveys. These metrics are helpful to national TB programs to assess the burden of disease, but they do not directly measure incident infection in the community.To estimate incidence of Mycobacterium tuberculosis infection in Kampala, Uganda, we performed a prospective cohort study between 2014 and 2017 which enrolled of 1,275 adult residents without signs of tuberculous infection (tuberculin skin test [TST] <5 mm and no signs of TB disease) and followed them for conversion of TST at 1 year.During follow-up, 194 participants converted the TST and 158 converted by one year. The incidence density of TST conversion was 13.2 conversions/100 person-year (95% CI 11.6-15.1), which corresponds to an annual cumulative incidence of tuberculous infection of 12.4% (95% CI 10.7-14.3). Cumulative incidence was greater among older participants and among men. Among participants who reported prior exposure to TB cases, the cumulative risk was highest among those reporting exposure during follow-up.The high annual incidence of infection suggests that residents of Kampala have adequate contact for infection with undetected, infectious cases of TB as they go about their daily lives..

Antibody Response Before and After the Booster Dose of Inactivated Corona Vaccine in Antibody Deficient Patients.

Patients with inborn errors of immunity (IEI) are among the high-risk groups regarding COVID-19. Receiving booster doses (third and fourth) in addition to the standard doses is recommended in these patients. This study investigated the antibody response before and after a booster dose of Sinopharm vaccine in IEI patients.  Thirty patients (>12 years) with antibody deficiencies, referred to Imam Khomeini Hospital and Children's Medical Center in Tehran, were enrolled in this prospective cross-sectional study. All patients were fully vaccinated with the BBIBP-CorV vaccine (2 doses of Sinopharm). Initial measurements of anti-receptor-binding domain (anti-RBD) and anti-nucleocapsid (anti-N) IgG antibody responses were conducted by enzyme-linked immunosorbent assay (ELISA). Subsequently, all patients received a booster dose of the vaccine. Four to six weeks after booster injection, the levels of antibodies were re-evaluated.  Twenty patients with common variable immunodeficiency (CVID), 7 cases with agammaglobulinemia and 3 patients with hyper IgM syndrome were studied. Anti-RBD IgG and anti-N IgG antibodies increased in all patients after the booster. Our results indicated the need of receiving booster doses of the COVID-19 vaccine in patients with antibody deficiencies, even for enhancing humoral immune response specially in patients with CVID.

Tamsulosin 0.8 mg daily dose in management of BPH patients with failed tamsulosin 0.4 mg monotherapy and unfit for surgical intervention.

AIM: This study aims to evaluate the effectiveness and safety of administering double-dose tamsulosin (0.8 mg) for treating patients with benign prostatic hyperplasia (BPH) who have not responded to the standard single dose of tamsulosin (0.4 mg) and are deemed unsuitable for transurethral resection (TUR) intervention. MATERIALS AND METHODS: Between November 2022 and July 2023, we prospectively analyzed 111 patients who were experiencing severe BPH symptoms. These patients received a double dose of tamsulosin for one month. We collected baseline characteristics such as age, body mass index, and underlying medical conditions. Various parameters including the International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA) levels, prostate volume, peak urinary flow rate (Qmax), voided volume, and post-void residual volume were evaluated before and after treatment. RESULTS: All 111 patients completed the study. The mean age, PSA level, and prostate volume were 63.12 ± 4.83 years, 3.42 ± 0.93 ng/ml, and 50.37 ± 19.23 ml, respectively. Of these patients, 93 showed improvement in Qmax, post-void residual volume, and IPSS score (p-value = 0.001). The total IPSS score and total Qmax improved from 24.03 ± 2.49 and 7.72 ± 1.64 ml/sec to 16.41 ± 3.84 and 12.08 ± 2.37 ml/sec, respectively. CONCLUSION: Double-dose 0.8mg tamsulosin as an alpha-blocker therapy appears to be a viable temporary management option for BPH patients who have not responded to the standard single dose 0.4mg tamsulosin and are not suitable candidates for TUR intervention.

Normal range and risk factors for deviating body temperatures during the first 24 hours in term-born infants under standardised care: an observational study.

OBJECTIVE: Body temperature for a known ambient temperature is not known for infants born at term. We aimed to determine the normal range and the incidences of hypothermia and hyperthermia during the first 24 hours of life in healthy term-born infants nursed according to WHO recommendations. DESIGN: Prospective observational study. SETTING: Norwegian single centre district hospital. Infants were observed during skin-to-skin care or when dressed in cots. PARTICIPANTS: Convenience sample of 951 healthy infants born at term. METHODS: Delivery room temperature was aimed at 26-30°C and rooming-in temperature at 24°C. We measured rectal and room temperatures at 2, 4, 8, 16 and 24 hours of age. MAIN OUTCOME MEASURES: Percentile curves for rectal temperature. Proportions and risk factors for hypothermia and hyperthermia. RESULTS: The mean (SD) room temperature was 24.0°C (1.1), 23.8°C (1.0), 23.8°C (1.0)., 23.7°C (0.9) and 23.8°C (0.9). The median (2.5, 97.5 percentile) rectal temperature was 36.9°C (35.7-37.9), 36.8°C (35.9-37.5), 36.9°C (36.1-37.5), 37.0°C (36.4-37.7) and 37.1°C (36.5-37.7). Hypothermia (<36.5°C) occurred in 28% of the infants, 82% of incidents during the first 8 hours. Risk factors for hypothermia were low birth weight (OR 3.1 (95% CI, 2.0 to 4.6), per kg), male sex, being born at night and nursed in a cot versus skin to skin. Hyperthermia (>37.5°C) occurred in 12% and most commonly in large infants after 8 hours of life. Risk factors for hyperthermia were high birth weight (OR 2.2 (95% CI, 1.4 to 3.5), per kg), being awake, nursed skin to skin and being born through heavily stained amniotic fluid. CONCLUSIONS: Term-born infants were at risk of hypothermia during the first hours after birth even when nursed in an assumed adequate thermal environment and at risk of hyperthermia after 8 hours of age.

A real-life study of daratumumab combinations in newly diagnosed patients with light chain (AL) amyloidosis.

Daratumumab-based regimens are the new standard of care for newly diagnosed patients with AL amyloidosis based on the results of the ANDROMEDA study. However, real-world data on daratumumab efficacy in upfront therapy in unselected patients are scanty. In the framework of a prospective observational study, we investigated the efficacy and safety of daratumumab in 88 newly diagnosed patients, including subjects with IIIb cardiac stage (26%) or myeloma defining events (29%). Daratumumab was administered with bortezomib in 50 (56%) patients, lenalidomide in 31 (35%), and monotherapy in 7 (8%). The rate of serious adverse events was low (16%). The overall hematologic response rate was 75% with 52 (59%) patients attaining at least a very good partial response (VGPR) at six months. Amongst patients evaluable for organ response, the rate of cardiac and renal responses at 6 months was 31% and 21%, respectively. Comparing stage IIIb patients with the remaining ones, the rate of profound hematologic response was not significantly different (≥VGPR 57% vs. 59%, p 0.955) likewise the rate of cardiac (33% vs. 30%, p 0.340) and renal (40% vs. 16%, p 0.908) responses. Daratumumab-based regimens demonstrated to be safe and effective in treatment-naïve AL amyloidosis even in advanced stage disease.

The role of familial factors and neuroticism in the association between exposure to offensive behaviors at work and long-term sickness absence due to common mental disorders - a prospective twin study.

OBJECTIVES: The aim of this study was to investigate associations between exposure to work-related violence/threats and harassment, and future sickness absence (SA) due to common mental disorders (CMDs), taking familial factors (shared genetics and early-life environment) and neuroticism into account. METHODS: The study sample included 8795 twin individuals from the Swedish Twin Project of Disability Pension and Sickness Absence (STODS), including survey data from the Study of Twin Adults: Genes and Environment (STAGE). Self-reported work-related violence and/or threats as well as work-related harassment (including bullying) and national register data on SA due to CMDs were analyzed using standard logistic regression, and conditional logistic regression among complete twin pairs discordant on exposures. Individuals were followed for a maximum of 13 years. Interactions between neuroticism and exposures were assessed using both multiplicative and additive interaction analyses. RESULTS: Exposure to work-related violence/threats was associated with higher odds of SA due to CMDs when adjusting for age, sex, marital status, children, education, type of living area, work characteristics, and symptoms of depression and burnout (OR 2.11, 95% CI 1.52-2.95). Higher odds of SA due to CMDs were also found for exposure to harassment (OR 1.52, 95% CI 1.10-2.11) and a combined indicator of exposure to violence/threats and/or harassment (OR 1.98, 95% CI 1.52-2.59), compared with the unexposed. Analyses of twins discordant on exposure, using the unexposed co-twin as reference, showed reduced ORs. These ORs were still elevated but no longer statistically significant, potentially due to a lack of statistical power. No multiplicative interaction was found between neuroticism and exposure to work-related violence/threats, or harassment. However, a statistically significant additive interaction was found between neuroticism and exposure to violence/threats, indicating higher odds of SA due to CMDs in the group scoring lower on neuroticism. CONCLUSIONS: Exposure to work-related offensive behaviors was associated with SA due to CMDs. However, the results indicated that these associations may be partly confounded by familial factors. In addition, an interaction between exposure and neuroticism was suggested. Thus, when possible, future studies investigating associations and causality between offensive behaviors at work and mental health-related outcomes, should consider familial factors and neuroticism.

Maximum surgical blood ordering schedule for elective surgical procedures in Omdurman teaching hospital, Sudan.

BACKGROUND: The need for blood during a surgical procedure is greater than what blood banks are able to provide. There is an excessive amount of blood being ordered for elective surgeries, surpassing the actual requirements. Only 30% of the cross matched blood is actually used in these surgeries. The accuracy of estimating the transfusion needs before a surgical procedure can be determined by looking at the cross match to transfusion ratio and the transfusion index. "These indicators play a crucial role in developing the maximum surgical blood ordering schedule; in this study, these indicators were tested." AIM OF STUDY: Is to determine the efficiency of blood ordering and transfusion practices for patients undergoing elective surgeries. METHODS: This study is a prospective cross-sectional hospital-based study done at Omdurman Teaching Hospital-Sudan. Conducted for the duration of 6 months period from July to December 2019.The study participants were patients who underwent elective surgical procedures in general surgery and Urology departments as total coverage sample over a period of study duration. Ethical clearance obtained from ethical committee of Sudan Medical Specialization Board. RESULTS: Two hundreds seven patients included in this study, the amount of blood units requested were 443-unit, cross matching for 98.6% (n 437) of units were done. Only 100 unit were Transfused (22,8%). The calculated CT ratio was 4.4, transfusion index was 1.6 and transfusion probability was 29.9%. CONCLUSION: Transfusion probability and transfusion index of the present study were optimal but comparatively higher than the standard guidelines as most of the cross matched blood was not utilized.

Morbidity and mortality of elderly patients with pancreaticobiliary disease according to age and comprehensive geriatric assessment: A prospective observational study / Morbilidad y mortalidad de pacientes de edad avanzada con enfermedad pancreaticobiliar con relación a su edad y la evaluación geriátrica integral: un estudio prospectivo observacional

Background This study was designed to analyze the influence of age and comprehensive geriatric evaluation on clinical results of pancreaticobiliary disease management in elderly patients. Methods A prospective observational study has been undertaken, including 140 elderly patients (over 75 years) with benign pancreaticobiliary disease. Patients were divided according to age in the following groups: group 1: 75–79 years old; group 2: 80–84 years old; group 3: 85 years and older. They underwent a comprehensive geriatric assessment with different scales: Barthel Index, Pfeiffer Index, Charlson Index, and Fragility scale, at admission and had been follow-up 90 days after hospital discharge to analyze its influence on morbidity and mortality. Results Overall, 140 patients have been included (group 1=51; group 2=43 and group 3=46). Most of them, 52 cases (37.8%), had acute cholecystitis, followed by 29 cases of acute cholangitis (20.2%) and acute pancreatitis with 25 cases (17.9%). Significant differences has been observed on complications in different age groups (p=0.033). Especially in patients with a Barthel Index result ≤60, which suggests that these less functional patients had more severe complications after their treatment (p=0.037). The mortality rate was 7.1% (10 patients). Conclusions No significant differences were found between age, morbidity and mortality in elderly patients with pancreaticobiliary disease. Comprehensive geriatric scales showed some utility in their association with specific complications. (AU)

Antecedentes Este estudio fue diseñado para analizar la influencia de la edad y la evaluación geriátrica integral en los resultados clínicos del manejo de la enfermedad pancreatobiliar en pacientes de edad avanzada. Métodos Se ha realizado un estudio observacional prospectivo en el que se incluyeron 140 pacientes de edad avanzada (mayores de 75 años) con enfermedad pancreatobiliar benigna. Los pacientes se dividieron según la edad en los siguientes grupos: Grupo 1: 75-79 años; Grupo 2: 80-84 años; Grupo 3: 85 años y más. Se les realizó una valoración geriátrica integral con diferentes escalas: Barthel Index, Pfeiffer Index, Charlson Index y Fragility scale, al ingreso y seguimiento 90 días después del alta hospitalaria para analizar su influencia en la morbimortalidad. Resultados En total, se incluyeron 140 pacientes (Grupo 1=51; Grupo 2=43 y Grupo 3=46). La mayoría de ellos, 52 casos (37,8%), presentaron colecistitis aguda, seguido de colangitis aguda con 29 casos (20,2%) y pancreatitis aguda con 25 casos (17,9%). Se han observado diferencias significativas en las complicaciones en diferentes grupos de edad (p=0,033). Especialmente en pacientes con un índice de Barthel ≤60, lo que sugiere que estos pacientes menos funcionales tuvieron complicaciones más severas después de su tratamiento (p=0,037). La tasa de mortalidad fue de 7,1% (10 pacientes). Conclusiones No se encontraron diferencias significativas entre la edad, la morbilidad y la mortalidad en pacientes ancianos con enfermedad pancreatobiliar. Las escalas geriátricas integrales mostraron cierta utilidad en su asociación con complicaciones específicas. (AU)

Evaluation of tolerance to mercaptopurine in patients with inflammatory bowel disease and gastrointestinal intolerance to azathioprine / Evaluación de la tolerancia a la mercaptopurina en los pacientes con enfermedad inflamatoria intestinal e intolerancia gastrointestinal a la azatioprina

Background Thiopurines such as azathioprine (AZA) and mercaptopurine (MP) are commonly utilized to treat inflammatory bowel disease (IBD). Their use is frequently restricted due to gastrointestinal intolerance (GI). Previous retrospective studies have reported that AZA-intolerant patients may benefit from a switch to MP; yet the effectiveness of this strategy has not been prospectively evaluated.AimsTo assess GI tolerance to MP in patients who are intolerant to AZA, and to identify clinical predictors of GI intolerance to AZA or MP.MethodsA prospective, observational, single-cohort study was performed in 92 thiopurine-naïve IBD patients. They were started on a 50mg dose of AZA and escalated to 2.5mg/kg per day by week 2. Those with GI intolerance were rechallenged with a 50% dose of AZA, after which another dose escalation attempt was made. If symptoms persisted, they were switched to MP.ResultsThirty (32.6%) of the recruited patients suffered from GI intolerance to AZA. Of these, 15 did not present recurrence of symptoms after rechallenge with lower doses. Of 15 intolerant patients, 14 were switched to MP. Within the MP cohort, 8 patients (57%) were also intolerant to MP, 5 (36%) had no symptoms, and 1 (7%) was lost to follow-up. Female gender was the only independent predictor of GI intolerance to AZA.ConclusionsUp to half of the AZA-intolerant patients tolerated a 50% dose rechallenge that was successfully escalated. A switch to MP was tolerated in over a third of cases whom rechallenge failed. Our strategy (challenge–rechallenge–switch) achieved an overall GI tolerance to thiopurines in most of the patients. (AU)

Antecedentes Las tiopurinas como la azatioprina (AZA) y la mercaptopurina (MP) se utilizan comúnmente para tratar la enfermedad inflamatoria intestinal (EII). Su uso está frecuentemente restringido debido a la intolerancia gastrointestinal. Estudios retrospectivos anteriores han informado que los pacientes intolerantes a la AZA pueden beneficiarse de un cambio a MP; sin embargo, la eficacia de esta estrategia no ha sido evaluada prospectivamente.ObjetivosEvaluar la tolerancia gastrointestinal a MP en pacientes que son intolerantes a AZA e identificar predictores clínicos de intolerancia gastrointestinal a AZA o MP.MétodosSe realizó un estudio prospectivo, observacional y de cohorte única en 92 pacientes con EII que nunca habían recibido tiopurinas. Comenzaron con una dosis de 50mg de AZA y se aumentó a 2,5mg/kg por día en la semana 2. En aquellos con intolerancia gastrointestinal se administró una dosis del 50% de AZA que se fue incrementando en función de la tolerancia. Si los síntomas persistían, se cambiaba a MP.ResultadosTreinta (32,6%) de los pacientes reclutados presentaron intolerancia gastrointestinal a la AZA. De estos, 15 no presentaron recurrencia de los síntomas después de la nueva exposición. De los 15 pacientes que no toleraron una dosis más baja, 14 recibieron MP. De los que recibieron MP, 8 pacientes (57%) también eran intolerantes a MP, 5 (36%) no tenían síntomas y uno (7%) se perdió durante el seguimiento. El género femenino fue el único predictor independiente de intolerancia gastrointestinal a la AZA.ConclusionesHasta la mitad de los pacientes intolerantes a la AZA toleran una nueva exposición al 50% de la dosis. Se toleró un cambio a MP en más de un tercio de los casos en los que la reexposición fracasó. Nuestra estrategia logró la tolerancia gastrointestinal a tiopurinas en la mayoría de los pacientes.

Cytokine profiles in dengue fever and dengue hemorrhagic fever: A study from Indonesia.

Recent studies have demonstrated that cytokine dysregulation has a critical role in the pathogenesis of dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). The aim of this study was to investigate the association between tumor necrosis factor (TNF- α), interleukin 6 (IL-6), interleukin 10 (IL-10), and interleukin 17 (IL-17) with infection status, and severity of dengue. A prospective cross-sectional study was conducted at three hospitals in Gianyar regency and Denpasar municipality, Bali, Indonesia, from June to December 2022. Sixty-four dengue infected patients were involved. Patients' serum was tested for dengue infection using NS1 antigen rapid test, dengue virus immunoglobulin M (IgM) and immunoglobulin G (IgG) test, and reverse transcription polymerase chain reaction (RT-PCR). Cytokine levels (TNF-α, IL-6, IL-10, and IL-17) were measured using enzyme-linked immunosorbent assay (ELISA). Infection status was determined by combining serological and RT-PCR results, categorizing patients into primary and secondary infections. The present study found that DF patients had lower TNF-α, IL-6, and IL-17 but higher IL-10 levels compared to DHF patients (p<0.001). Elevated TNF-α, IL-6, and IL-17 levels were higher in secondary infection, while IL-10 level was higher in primary infection (p<0.001). In conclusion, cytokines play a crucial role in the interplay between cytokine dysregulation and dengue infection dynamics.

Association between NT-proBNP level and the number of stents with major advanced cardiovascular events (MACE) in patients with multivessel coronary artery disease treated with percutaneous coronary intervention: A prospective cohort study.

Complex revascularization strategies, particularly complete revascularization, are controversial in coronary artery disease (CAD), and data supporting routine revascularization in stable CAD is lacking. The importance of percutaneous coronary intervention (PCI) in CAD and N-terminal pro-brain natriuretic peptide (NT-proBNP), which has been studied as a predictor of major advanced cardiovascular events (MACE) in CAD patients, still requires further research. The aim of this study was to determine the association between NT-proBNP levels and the number of stents with MACE incidence in CAD cases. A prospective cohort study was conducted in both types of CAD (acute coronary syndrome (ACS) and chronic coronary syndrome (CCS)). The NT-proBNP levels were measured pre- and post-PCI using fluorescence immunoassay, while MACE was assessed three months post-PCI. The Student t-test was used to compare the levels of NT-proBNP between pre- and post-PCI and between those who had MACE and did not; both in patients treated with single or multiple stenting groups. A total of 32 CAD patients were recruited, consisting of 20 ACS cases and 12 CCS cases. NT-proBNP levels post-PCI increased significantly in both ACS and CCS patients compared to pre-PCI either among those treated with single and multiple stentings. MACE occurred in 4 (12.5%) out of a total of 32 patients, all of which occurred in ACS patients treated with multiple stentings. Those who had MACE had higher post-PCI NT-proBNP levels compared to those who did not have MACE (23,703.50 vs 11,600.17 pg/mL, p=0.013). This study highlights the association between elevated NT-proBNP levels and multiple stenting with the presence of MACE in CAD patients, particularly in ACS cases.

Migraine and risk of atrial fibrillation: A 9-year follow-up based on the Trøndelag Health Study.

BACKGROUND: Data from some population-based studies have indicated an increased risk of atrial fibrillation (AF) among patients with migraine, particularly among individuals with migraine with aura. The present study aimed to assess the association between primary headache disorders and AF. METHODS: In a population-based 9-year follow-up design, we evaluated the questionnaire-based headache diagnosis, migraine and tension-type headache (TTH) included, collected in the Trøndelag Health Study (HUNT3) conducted in 2006-2008, and the subsequent risk of AF in the period until December 2015. The population at risk consisted of 39,340 individuals ≥20 years without AF at HUNT3 baseline who answered headache questionnaire during HUNT3. The prospective association was evaluated by multivariable Cox proportional hazard models with 95% confidence intervals (CIs). RESULTS: Among the 39,340 participants, 1524 (3.8%) developed AF during the 9-year follow up, whereof 91% of these were ≥55 years. In the multivariable analyses, adjusting for known confounders, we did not find any association between migraine or TTH and risk of AF. The adjusted hazard ratios (HRs) were respectively 0.84 (95% CI = 0.64-1.11) for migraine, 1.16 (95% CI = 0.86-1.27) for TTH and 1.04 (95% CI = 0.86-1.27) for unclassified headache. However, in sensitivity analyses of individuals aged ≥55 years, a lower risk of AF was found for migraine (HR = 0.53; 95% CI = 0.39-0.73). CONCLUSIONS: In this large population-based study, no increased risk of AF was found among individuals with migraine or TTH at baseline. Indeed, among individuals aged ≥55 years, migraine was associated with a lower risk for AF.

MUC5AC: A potential biomarker of severity in pediatric patients infected with influenza.

Numerous factors can increase the risk of severe influenza; however, a majority of severe cases occur in previously healthy children. Identification of high-risk children is important for targeted preventive interventions and prompt treatment. The aim of this study was to evaluate MUC5AC as a biomarker for influenza disease severity in children. For this, a prospective cohort study was conducted in 2019. Children hospitalized with acute respiratory infection (ARI) with confirmed positive influenza infection were enrolled. Influenza cases were identified by reverse transcriptase-polymerase chain reaction. Life-threatening disease (LTD) was defined by the need for intensive care and ventilatory support. MUC5AC, epidemiologic, and clinical risk factors were assessed. Three hundred and forty-two patients were hospitalized with ARI, of which 49 (14%) had confirmed influenza infection and 6 (12%) of them developed LTD. MUC5AC levels were higher in those patients with mild disease compared to cases with poorer outcomes. Our results show that the severity of influenza infection in children is significantly associated with low levels of MUC5AC. These findings suggest its potential as a suitable biomarker for predicting disease severity.
